The Harford County Sheriff’s Office says at least two men were involved in the robbery, which was timed for when the GameStop in Bel Air was about to close Saturday night.

The men, who were armed with guns, stole four cases full of the “Black Ops” game, which is the latest in the popular “Call of Duty” series. Cash and video game systems were also taken.

Sheriff’s office spokeswoman Monica Worrell says anyone who has the game before Tuesday shouldn’t have it and asked residents to call authorities if they’re offered copies of the game before it’s released.
